zany dog exploits – and other tails

I have a crystal pendant hanging in one window that throws a rainbow out across the room whenever the sunlight strikes it at a certain angle. It is a very pretty effect.

Above is the rainbow it casts on a coffee table.

As I have said in a previous post, Scattering Rainbows, you can split white light (sunlight) up into its constituent colours using a glass prism, (or crystal, as here). This was first done by Isaac Newton.

This lone dandelion caught my eye as I passed it on the steps. It was so white, not the gold I’m used to seeing in bright sunlight, and the rain had clumped the seeds together, making the ends look like wet feathers.

It didn’t matter to me that I did not plant it, nor that it is considered a weed. I admired its tenacity, flourishing there in the bricks.
